Hallo all ! My Dahlias ,I grew from seed also and some now even have buds on ....I have never grown Dahlias from seed before and I am amazed at how easily and quickly they all germinated , some have buds on ,but I too was wondering wether to pinch them back ? They are in a greenhouse with a little heater.....when can they (generally ) be put out to harden off please ? and thankyou Rohaise :)
